CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 468,271, dated February2, 1892.

Application filed January 2, 1891. Serial No. 376.561. (No model.)

To all whom it may concern:

Be it known that I, SwAN SwANsoN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, havenvented certain new and useful Improvenents in Cultivators; and Idohereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention consists in a new and improved cultivator which is lightand strong in its construction and exceedingly effective in itsoperation; and the invention will be hereinafter fully described andclaimed.

Referring to the accompanying drawings, Figure l is a side elevationshowing the carrying-wheels bearing the cultivator. Fig. 2 is a similarView showing the said wheels raised out of the way. Fig. 3 is a top planview. Fig. 4 is a detail View of the levercontrolling the tongue. Fig. 5is a transverse section of one of the rollers.

The same letters of reference indicate corresponding parts in all thefigures.

Referring to the several parts by letter, A indicates the floor orplatforn of the cultivator, and A' A' its side frames, in the lower partof which the rollers carrying the culti vator-teeth are nounted.

B B indicate the rollers,of which four are here shown employed, theserollers being .made of wood and having secured to their ends the metalcap-pieces or plates C, which are formed with the bearing-spindlesC',which fit and turn in bearings in the lower part of the side framesA' A'.

The double-ended cultivator-teetl D are square in cross-section and arepointed and sharpened at each end. These teeth are driven diametricallythrough the Wooden rollers B, so that their ends project for an equaldistance on both sides thereof, and the pointed ends of the teeth arecurved forward, as shown, so that in operation they will leave the earthin a Vertical line as the machine is driven forward and the rollersrevolve, as will be readily understood. Any number of rollers may ofcourse be employed, according to the size of the cultivatonframe.

E indicates the axle, which is nounted in bearings on the platform A, asshown, and

raised up above the ground, as shown in Fig.

1, when the hooked inner end H' of a pivoted spring-actuated foot-leverH is pressed into the recess F' of the cam F, and this locks the Wheelssecurely in this position. The machine can then be drawn along the roadwith- 4 out the teeth of the rollers coming in contact with the ground.hen the field is reached, it is only necessary to press down the outerend of the foot-lever with the foot to release its hooked end from thenotch F' when the weight of the nachine-body will lower it until theteeth D enter the ground, when the wheels E' will be raised up out ofthe way and will be held in that position by the hooked end of the levercatching in the recess F of the cam F.

On the under side of the inner end of the tongue I is bolted a castingJ, and a pivotbolt K passes through this casting and through the innerends of brackets L,bo1ted beneath the forward end of the platform A, theinner end of the tongue fitting and playing in a longitudinal recess Aformed in the under side of that end of the platform. The inner end ofthe tongue is connected by a chain M with a hand lev'er N, which ispivoted at its forward end to the top of the platform, as shown.

'When the body of the cultivator is raised to draw the machine along theroad, the inner end of the hand-lever N is raised and caught andsupported on the recessed upper end of a short Vertical post 0, thusraising the inner end of the tongue and holding the tongue firmly in ahorizontal position. Vlen, however, the cultivator is lowered into itsoperative position, the inner end of the hand-lever is disengaged fromthe recessed post O, leaving the inner end of the tongue free, so thatits outer end can rise and give when the IOO the cranked ends, theWheels nounted on said ends, the earn F, innovably secured on the axleand formed with the reoesses F' and 1 the raising and lowering lever G,secured to the axle, and the centrally-pivoted springactuatedfoot-level* H, formed With the inner looking end adapted to engage inthe recesses F' and F of the axle-cam F, substantially as set forth.

In testimony Whereof I affix my Signature in presence of two witnesses.
